fcavolo, which DAC are you using?
Fcavolo, could you please describe in detail what improvements you are hearing? You're the first on this thread hearing improvement in a DAC other than the Tranquility.
Huh?
Could you post a picture of the connection?
No need to fret, ted_b - their loss, your gain - get yourself one of these for $3 & supply your own low noise 5V supply (even batteries) http://www.streakwave.com/Itemdesc.asp?ic=5VUSBAnd still have lots of money left for music purchasing!
for cheapskates, there's an inexpensive linear PS I learned about recently that you should consider for powering USB devices with something other than the computer or the SMPS that came with the device.These little guys are so inexpensive, you should buy a handful - one per USB powered device - and then throw out all the USB switchers in the house (or at least in the mancave).http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_283573_-1BTW, they're only $10.95. They only provide 500 mA, which meets the USB bus power requirement (I believe). note: IMO, the majority of gains from using a linear PS in digital audio MAY BE from simply eliminating the SMPS. This is especially true for things like external hard drives, dedicated ripping drives, Apple SuperDrive, etc. which need noise-free, but not ripple-free, power to do their job (bit-)perfectly.
I learned about this PS listening to a prototype of Pat's (of AR-T) new USB isolation "black box" - which also provides 'clean' USB power. Highly recommended! This would seem to be a bargain for anyone investing (hopefully before such investment) in expensive USB cables and/or expensive USB power solutions. I believe it will go for $150 and should be available soon (if not already).It uses the ADuM4160 chip however, so it's limited to 96kHz. I didn't test what would happen with a file of higher than 96kHz sample rate, for the simple reason that I don't listen to any.
Great to see you around. Do you know if they have a 12VDC version?EDIT: They do have them...on the same page. Oh we know about it.... http://www.audiocircle.com/index.php?topic=96664.0
